Detailed Description

Noise removal filtering of an image using an adaptive Wiener filter with border control.

Pixels under the source mask are used to generate statistics about the local neighborhood which are then used to control the amount of adaptive noise filtering locally applied.

Currently only the NPP_BORDER_REPLICATE border type operation is supported.

Common parameters for nppiFilterWienerBorder functions include:

Parameters
pSrcSource-Image Pointer.
nSrcStepSource-Image Line Step.
oSrcSizeSource image width and height in pixels relative to pSrc.
oSrcOffsetThe pixel offset that pSrc points to relative to the origin of the source image.
pDstDestination-Image Pointer.
nDstStepDestination-Image Line Step.
oSizeROIRegion-of-Interest (ROI).
oMaskSizePixel Width and Height of the rectangular region of interest surrounding the source pixel.
oAnchorPositive X and Y relative offsets of primary pixel in region of interest surrounding the source pixel relative to bottom right of oMaskSize.
aNoiseFixed size array of per-channel noise variance level value in range of 0.0F to 1.0F.
eBorderTypeThe border type operation to be applied at source image border boundaries.
nppStreamCtxApplication Managed Stream Context.
Returns
Image Data Related Error Codes, ROI Related Error Codes

For each pixel in the source image the function estimates the local mean and variance in the neighborhood defined by oMaskSize relative to the primary source pixel located at oAnchor.x and oAnchor.y. Given an oMaskSize with width $W$ and height $H$, the mean, variance, and destination pixel value will be computed per channel as

\[Mean = \frac{1}{W\cdot H}\sum_{j=0}^{H-1}\sum_{i=0}^{W-1}pSrc(j,i)\]

\[Variance^2 = \frac{1}{W\cdot H}\sum_{j=0}^{H-1}\sum_{i=0}^{W-1}(pSrc(j,i)^2-Mean^2)\]

\[pDst(j,i) = Mean+\frac{(Variance^2-NoiseVariance)}{Variance^2}\cdot {(pSrc(j,i)-Mean)}\]
